We have presented in this article the general architecture of a participative simulation framework. It aims at easing the development of such simulators, more specifically by non-computer scientists. We analyzed the needs of such a framework, in particular from existing ad hoc participative simulators and highlighted that it should support remote collaboration, integration of various existing simulators and simulation platforms and should provide a multi-interface extension to these simulators.

From this analysis, we have designed a meta-model of participatory simulations that underlines these three features and translated it into a DTD. Finally we extended the PAMS portal to read the XML configuration files and display multiple interfaces for the simulators.

This work will be extended by improving the interactivity of our interfaces in order to improve the freedom of the stakeholders. Additional improvements will be induced by the actual and extensive use of the portal in modeling and simulation projects. Moreover we will need to build a specific modeling and simulation methodology that can take into account collaborative and remote tools such as the PAMS portal and its multiple-interface extension.
